Detecting object space with optoelectronic distance meter, involves calibrating distance measurement system with distance value determined by passing laser beam across reference object

摘要

The method involves using at least one of two scanner device deflection systems that is suitable for deflecting part of a laser beam to a reference object at a defined distance from a transmit and receive diode. A distance value determined by passing the beam across the reference object is used as a reference value for calibrating the distance measurement system. At least one deflection device is used for black or white image balancing.
